Will you please help me find this song?

I can't find this freaking song all I know is in part of the phrase a WOMAN is singing "She don't know~" and "He don't know~" and something like the word spaces? or places? or maybe even faces. I love the song and it's killing me not to know who sings it or even it's friggin title. It is not the Bon Jovi song nor is it the Usher song and I am sure It has come come in the latest few months of 2010. heeeeeelllp please!!!!
